AWR2243: Question about AWR2243 using DDMA

Part Number: AWR2243
Other Parts Discussed in Thread: AWR1243

Hi team,

We tried to implement DDMA using AWR2243, but the rlRfSetPhaseShiftConfig API does not execute on AWR2243 and returns error code 114.

My questions are：

  1. Does AWR2243 support the API rlRfSetPhaseShiftConfig ？
  2. If I want to use AWR2243 to implement DDMA, which API should I use？

 My mmwave SDK: mmwave_dfp_02_02_03_01

Thanks.

Regards,

Yafeng

    Hi Yafeng,

                   Yes the same API works for AWR224.

                   The error you are getting is: #define RL_RET_CODE_PERCHIRPPHSHIFT_UNSUPPORTED_DEV   (114U) /* API issued for non AWR1243/AWR2243 device */

                   Can you please make sure you are using the right device ID while passing the function?

                   Also, request you to please refer to the function: MmwDemo_configPhaseShifterChirps in C:\ti\mmwave_mcuplus_sdk_04_02_00_03\mmwave_mcuplus_sdk_04_02_00_03\ti\demo\awr294x\mmw\mss\mss_main.c for reference.

                 Let me know if you have any questions.

    Thanks and Regards,

    Akshay

    Hi Akshay

    Thank you for your support, the problem has been solved. The reason for the error is that I did not call rlRfSetMiscConfig before calling rlRfSetPhaseShiftConfig

    Thanks.
